a citizen ofthe llniteii tate. residing at Fort llorlzeje. in the county oic lrehster and State ot' lt ra. have iuwnteii certnin new :intl useful linproveniente in la'nrocltet-Gearing'. of which the 'toihwringj i5 a specification.

My invention relateaA io imprm'emenl's in sprocket gearing. and ia ilerifxal particularly for the purpoee ol trawaiitiing motion from a driving member to a i citen member. each of said memheral being' prorif'leil with a sprocket chain. ln the particular case illustrated. each sprockctclmin is equipped with an endless canvas heli paeaing ahout a roller, as itull)7 Sety i'orth in my pending application 'for Patent No.7l3, (i9 tilcil Sept.

The invention consist-s in certain novel 'features ot' construction anil comhinalional and arrangeinenta et parts. as hereinafter eety forth and claimeil.

ln the acecoiupanying drawings .l have liustrateci one complete example of the )hysical embodiment ot nn' invention con itructetl according` to the lit-2t motie l have So far devised -tor the practical application of the principle# ot the invention.

igin'e i is a sitle elevation o'f `the gearing'. Fig, '2 a View looking up from the hottom, and showing" one enti ot a pair ofi-ollers with belts passing thereover.

n the preferred einhctliinenty ot my invention l have illustrated two combined Sprocket ancl gear wheels l anti l, an@l these Wheels are adapted to rotate the rollers 2 and 2a over which the canvas belts 3 and 3f" paras. l.While I hare illustrated the gearing applied to rollers anti helts, it will ot' course he understood that l contemplate. being in v gearing' in other relations and upon other suitable structures or machines where applicable.

Each of the sprocket-gear Wheels is provided with sprocket teeth 4. l to accommodate thel chains 5. 5a. The links` are similar throughout the chains` hut for convenience of description l shall designate them as 6, (la ot the reepectii'e chainsl fitting over the aprocl-:et teeth. el, 4a. and links T. Tjlitting over the (louhle teeth tl. between which thc .soeketal l). D are formed for the reception of the. teeth l. la. The pins 10, to hohl the chaine' together and complete he linka which paas over the teeth ot the wheels.

The arrows indicate thedirectionofniovenient et the wheels. and it is assumed that the. wheel 1 is the driving wheel, receiving power from a suitable Source not shown, and transmitting power to the driven Wheel direct. anal through the Laprecket chains these wheels transmit the power to a second pair et sprocket. wheels,

From the ahoie description taken in connection with the tlrawingrs` ity evident that, I hare proriclefljan etlicienty and economical combination of elements for the frana-ini ion ot power as described.

llavingr thun fully (leacrihetl my invention` what T claim aS new and desire. to secure h v 'lhe combination of a pair or' wheels each havingr a laeries of long teeth, and' a h eriee ot shorter teeth toi-ming sockets alternating with the long` teeth for the reception ot' the longP teeth on the opposite Wheel, a chain on each wheel passing over the long teeth as -api-tickets, and the long teeth passing through the chain when engaging the complementary sockets.

ln testimony ii'hereof I atiix my signature in presence of tivo witnessee.
